NASA Space Station On-Orbit Status 24 March 2020 – Ultrasound Scans and Eye Checks
NASA Space Station On-Orbit Status 24 March 2020 - Ultrasound Scans and Eye Checks.

Ultrasound scans and eye checks aboard the International Space Station today are helping doctors understand how the Expedition 62 crew is adapting to microgravity.
Back on Earth, a new crew is in final preparations for its launch next month.

NASA Flight Engineer Jessica Meir spent Tuesday morning on biomedical duty and scanned her leg arteries with an ultrasound device. She also attached electrodes to her neck, thigh and heart for the Vascular Echo study. Flight surgeons on the ground monitor the scans real-time to glimpse a crewmember’s heart and blood vessel health in space.

In the afternoon, Meir joined fellow Flight Engineer Andrew Morgan for eye exams. The duo took turns imaging each other’s eyes using optical coherence tomography gear commonly found in an eye doctor’s office. Eye health in space is important, as some astronauts have reported experiencing vision problems after returning to Earth.

Morgan started the morning swapping out batteries in a device that analyzes the station’s atmosphere. Afterward, he tended to hardware for an experiment that seeks to improve the manufacturing process of metallic alloys on Earth.

All three crewmates, including Commander Oleg Skripochka, started the day readying their Soyuz MS-15 crew ship ready for departure on April 17. They performed a fit check of the Soyuz seats they will be sitting in for the three-and-a-half hour ride back to Earth.

Meanwhile, the crew that will replace them is nearing its launch scheduled for April 9 aboard the Soyuz MS-16 crew ship. NASA astronaut Chris Cassidy and Roscosmos cosmonauts Anatoly Ivanishin and Ivan Vagner arrived today at the Baikonur Cosmodrome in Kazakhstan for final training. The Expedition 63 trio is due to live aboard the station for 195 days with Cassidy as commander.

On-Orbit Status Report

Transparent Alloys-SEBA: The crew successfully exchanged the Transparent Alloys Cartridge. The aim of the Transparent Alloys-SEBA (Solidification along an Eutectic Path in Binary Alloys) experiment is to study the morphological instabilities of directional solidified, transparent binary eutectic alloys under purely diffusive conditions. This experiment provides a real-time observation of the dynamics of eutectic front structures with a micron-scale resolution, over a large (centimetric) space scale, and over long (several 10 hours) periods of time. These observations are strongly sensitive to convective motions in liquid, which, in ordinary conditions on earth, entail a detrimental redistribution of the solute on a scale comparable to the container size. Such convective motions are suppressed in microgravity.

Vascular Echo: The crew performed an ultrasound using ECHO for a resting position session #2. Blood Pressure measurements were also taken. Cardiac and Vessel Structure and Function with Long-Duration Space Flight and Recovery (Vascular Echo) examines changes in blood vessels, and the heart, while the crew members are in space, and then follow their recovery on return to Earth. The results could provide insight into potential countermeasures to help maintain crewmember health, and quality of life for everyone.

Rhodium Space Microbiome: The crew inserted Chamber (s/n 0006) from the SABL incubator into cold stowage. Genomics Investigation of Human Gut Microbiome to Determine Effects of Microgravity Exposures (Rhodium Space Microbiome) examines the effects of spaceflight on the human gut microbiome, a complex community of numerous bacterial species. Developing a better understanding shifts in microbiome diversity and function and how they affect human health and performance may help protect people on future missions. Recent studies have shown a connection between alterations in the structure and function of the gut microbiome and multiple chronic and acute diseases.
